En studie av VARIPULSE-kateter hos deltagare med bestående förmaksflimmer som genomgår isolering av lungvena och vena cava superior (SPAA PFA)

2 november 2026 uppdaterad av: Biosense Webster, Inc.

Bedömning av säkerheten och effektiviteten hos VARIPULSE™ katetersystemet vid behandling av deltagare med persisterande förmaksflimmer som genomgår isolering av lungven (med eller utan bakre väggisolering) och isolering av översta hålvenen: En randomiserad kontrollerad studie

The purpose of this study is to assess how safe VARIPULSE catheter system is for treatment of a heart rhythm disease called persistent atrial fibrillation (PsAF) in participants who are having a catheter ablation procedure (treat heart rhythm disease). This includes isolation of pulmonary vein and superior vena cava (heart veins; pulmonary vein isolation [PVI] and superior vena cava isolation [SVCI]), with or without another technique called posterior wall isolation (PWI). Also, to assess how safe it is for participants who are having a catheter ablation procedure and at the same time receiving another procedure called left atrial appendage occlusion (LAAO; to reduce stroke risk). Additionally, to assess how well VARIPULSE catheter system works over a long period of time for treatment of PsAF in participants undergoing catheter ablation for PVI, SVCI and SVCI+PWI.

Experimentell: VARIPULSE Catheter System: PVI and SVCI

Participants with persistent atrial fibrillation (PsAF) undergoing catheter ablation for the first-time with the VARIPULSE Catheter System will undergo the ablation procedure for PVI and SVCI.

Additionally, a subset of participants will undergo a concomitant left atrial appendage occlusion (LAAO) procedure. All participants will be followed for up to 36 months post procedure.

Pulsed field ablation by VARIPULSE Catheter System (VARIPULSE bi-directional catheter and TRUPULSE generator) will be used.

LAAO procedures will be performed using commercially available LAAO devices in accordance with the device's instruction for use (IFU).

Experimentell: VARIPULSE Catheter System: PVI and SVCI + PWI

Freedom from Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia Episodes
Tidsram: Day 61 up to Day 365

Number of participants reporting freedom from documented (symptomatic and asymptomatic) atrial tachyarrhythmia (that is, AF, AT or AFL of unknown origin) episodes based on electrocardiographic and freedom from acute procedural failure, repeat ablation failure, surgical treatment for AF/AT/AFL, NSC failure, AAD failure and any DC cardioversion (DCCV) procedure.

Change From Baseline in Quality of life, As Measured by the Total Atrial Fibrillation Effect on Quality-of-Life (AFEQT) Score
Tidsram: Baseline, at 12 months post-procedure

The AFEQT uses a questionnaire to evaluate symptoms, daily activities and treatment concerns participants have related to atrial fibrillation. An overall AFEQT score ranges from 0 to 100. A score of 0 corresponds to complete disability (or responding "extremely" difficult to all questions answered), while a score of 100 corresponds to no disability (or responding "not at all" limited, difficult or bothersome to all questions answered). A positive change in score corresponds to improvement in AF symptoms.
